<p>
<code>display <i>expression</i></code><br>
or<br>
<code>d <i>expression</i></code>

<p>
The <code>display</code> command is how you actually display data via the
graphics output window. <p>

<H3>Usage Notes</H3>
<P>
If you <code>display</code> when all dimensions are fixed, you get a
single value which is typed out in the command window. If you
<code>display</code> when one dimension varies, you get a 1-D line
graph (by default). If you <code>display</code> when two dimensions
are varying, you get a 2-D contour plot (by default).
<p>
GrADS will automatically overlay the output from each successive
display command.<br>
To clear the display, enter: <p>

<dd>
<code>clear</code> (or just <code>c</code>) 
</dd>

<p>
<H3>Examples</H3><P>

The simplest example of an expression to display would be a variable named by the default data file.<br>
